Of course not, but besides 3D displays and touch sensing controllers there aren't many options out there. And we have to be realistic here: I certainly doubt Nintendo will break completely with the technology that sold a royal ass ton of Wiis.

I'm hoping Nintendo dazzles us with something *useful*.

I'll stay away from this, the definition of useful is absolutely subjective. IMHO, motion sensing controllers have a lot to offer besides generic waggling (a horrible tendency among Wii games, I must admit). See WarioWare Smooth Moves and tell me how can I do that with a 360 Controller.

In any case, my point was that to have games like Mass effect or Oblivion, you only need a more powerful Wii
